-' To all whom it may concern:

1 B81 it .known that IiWVAnrnn Dosr, a;citi-H zen of the United States and a resident of Yuba City, .countyofSutter and State of fllcalifornia, have invented aenewmand use ful Checkmg'Implement, of whlch the followingis a specification.

i The present invention relates to improve- .ments inche-ckers adapted to be used for the -throwing up of checks or levees in preparing agricultural land for irrigation.

- checking implement that will; allow a check or levee to be thrown up in asinglevcon- .tinuous operation, that requires comparatively' little power andis capable ofvarious A adjustments. It is particularly proposed tou provide. an implement 0 .613116] character clescribed that may be attached to a tractor or other pulling agent in such manner that the pulling force is properly distributed so that it is-iunnecessary to apply welghts o-rthe like w formiamtainingthe operative engagement of certain parts of the implement with the-soil} m be handled@ It is further proposed to ,i provide means whereby the distribution ofv w-forcesmay be readily controlled inraccord- Lance :with the --requirements of each-case. Further objects and advantageswill appear.

as :the; specification proceeds.

1 :The preferred 1 form-of the invention isv ;I-illustrated in the accompanying drawings in; ww hich :Figure L-shows a plan View of ;my,\

be made within the scope of the claims heretoiattachednwithout departing from the spirit of the invention.

In my checker two plates (1) and (2), disposed in spaced relation to one another are curved to present their hollow faces inwardly. Each plate has two bands (3) and (4) secured to the outside and the bands are adapted'to be secured to two cross bars (6) and (7 in such a manner that the two plates converge toward the rear. As means for se curing the plates to the cross bars I preferably employ bolts (8) engaging corresponding perforations in the bands and the cross members, a plurality of perforations (9) be- The prin-. scipalobject oft'he invention is to provide a ing providedon the cross members to render the engagement.adjustable.

The vplatesare formed to, present in their *frontlportions parallel topfand bottomedges :(11): and (12) whilethe' rear ends of the bottom -.edges slant upwardly assho'wn at (13). Suitable blades (14) areremovably secured to .the lower edges oftheplates by means of bolts (16). They extend only through tlie'front portion of the plate while,

therear portions, which are not intended to scrape'and loosen dirt are not provided with blades. f i

. The principal vpart fof the present inventionisthe manner in which my implement 71s attaehedto a tractor or other pulling agent. Two rods (17) and (18) ,arefpivoted to.tl1e.1nner.faces of thentwo plates near their front ends and thefree ends 'of the two rods engage a ring adapted, to be se; I cured to the draw barof a, tractor notshown ain theldrawing. ',A third rod or bar (19),

preferably bent aslshown-at (21),, is] pivotally, secured with onevend tovthe rearcross .bar,(6) and withitsother end tethering (l9)bymeans of a clevis,o(22).f-It should be noted thaewhile the two,rods(17) and (18) engage the plates near theirrespective centers the .bar (19 engages the cross bar (6) it above the plates solthat when a forward pull is: exerted on the ring (19)},alonga line passingthrough the center of gravityjof-the device this coupling-has a tendency to exert slightrbutamay be. increased forcing the front endofthe bars (19) downward and in thelatter caseimay belincreased to such an extent, that the, front, end "of the, ,checker is lifted loft the, ground. ,t J' Toallowofsuchjadjustment of the,lower endjoflthe .bar (19) I ,jprovide a vertical guideway '(23) comprising a U-shaped member (24) engaging the lower face of the frontcross bar (7) with its back and having its legs turned as shown at (26) so as to slant upwardly and to return to the cross bar (7) to be secured by means of bolts (27). In the two legs (23) and (24) is supported a pin (28) on which pivots a lever (29) bent as shown at (31) so as to be adapted to be forced downwardly and to depress the bar (19). A plurality of perforations (32) are provided in the legs of the U-shaped member (23) so as to allow the pin (28) to be lowered and raised. A second pin (33) engaging a shoulder (34;) on the lever may be employed to hold the latter in place.

If desired my implement may be sup;

ported on wheels (36). For this purpose I provide brackets (37) extendingroutwardly from the two blades (1) and (2) and terminating in bearings (38) in which are journaled shafts (39), each having a lever arm "(41) extending from one end and a short arm (A2) extending from the other end in the opposite direction, which latter arm terminates in a'transverse shaft (43) forming the axle for the wheel By swinging the lever arm (4-1) on its pivot the wheels (36) may be forced downwardly to lift the rear end of the implement off the "ground so that when pull is exerted at along the curved faces of the two plates. Only the front end of the implement engages all the dirt while the rear end engages only the upper-portion of the same so as to form a ridge. Considerable power is saved due to this arrangement. It will be noted that 1 while the general arrangement of the plates is such as to force the dirt inwardly the lower rear corners (46) of the plates flare outwardly so as to glide over the dirt easily. By means of my attachment the.

pulling forces may be distributed in such a manner that therear end is acted on simultaneously with the front end and is forced downwardly during the checking operation by the direct pull which makes it unnecessary to place any weights on the same.

Turning operations are also facilitated by my attachment since the front end of the bar (19 may be lowered-to such an extent by means of the lever (29) that the front end of the implement is j practically lifted off the ground so that the whole implement slid-es on the rear end without performing any work. The two plates may be set to any width desired in accordance with the size of dam which it is intended to produce.

The particular form of each plate resembles the mold board of a plow and performs the same function allowing the dirt to be turned over gradually rather than to be pushed sideways.

I claim:

1. A checking implement of the character described, comprising two cooperating elements arranged to 'force dirt inwardly when dragged forward, a front and a rear 'bar bridging the same and holding them in spaced relation, and means for attaching the same to a pulling agent comprising a member engaging the pulling agent, two rods loosely connecting the same with the front ends of the two elements, a third rod connecting the same to the rear bar and adjustable means associated with the front bar bearing on the third rod for controlling the height of its front end.

2'. A checking implement of the character describe-d, comprising two cooperating elementsarranged to force dirt inwardly when dragged forward, a front and a rear bar bridging the same and holding them in spaced relation, and means for attaching the same-to a pulling agent comprising a member engaging the pulling agent, two rods loosely connecting the same with the front ends of the two elements, a third rod connecting the same to the rear bar guide means associated with the front bar straddling the third rod and a lever pivoted therein for controlling the height of its front end.

3. A checking implement of the character described, comprising two self-supporting cooperating elements arranged to force dirt inwardly when dragged forwardly and means for attaching the same to a pulling agent comprising means for connecting the front end to the pulling agent, means for independently connecting the rear end to the pulling agent and regulating means bearing onthe latter means for distributing the traction between the two means.
